You may get to Nessingwary's Retreat by traveling from Razik Gazdard, go into Totem del Fulmine, then leave a north-west bridge and path towards 41.78, 52.81 - which is just across from a beaver's damn construction.

Hemet Nesingwary can be found at 40.0 52.2 point in Nesingwary retreat area. Each addon during BC, there's Nesingwary quest hub can be found. Quest chains consist of hunting for mobs quests. So, Nesingwary in Legion can be found in Highmountain.You may flight from Stonehoof watch to The Thundet Totem.

Dudes, don't theorize too much on this champion. I did too confused and frightened by the comments here on how you can lose the breadcrumb quests and never get this champion. Do you really believe that Blizzard will make this so unfriendly? I even raised a ticket to ask the GMs who and first time they gave me this link (lol) and the next guy told me - "just go on and do your quest". I said "f$@# it" and did the Nessingwary quests for 15 minutes and boom - 2 followers. Hemet and Addie.
